Start clean, steady white noise in one tap. Mask voices, traffic, and household sounds with an even sound floor that helps you fall asleep faster and stay focused while you work.

White noise spreads sound energy evenly across the audible spectrum, so every frequency from low rumbles to high hiss is present in equal amounts. The result is a clean, steady texture that sounds a little like an old TV tuned to static or a strong air vent. Because nothing in the signal stands out, your brain stops scanning the room for new sounds. That is the entire trick — when there is no contrast between silence and sudden noise, sudden noises lose most of their power to pull you back into alert mode.
Studies have shown that adding a steady sound floor can shorten the time it takes to fall asleep by a noticeable margin, especially in noisy environments. White noise is the most aggressive masker of the colored-noise family, so it tends to work best when the sounds you want to cover are sharp, sudden, or unpredictable: voices through a wall, dishes in a shared apartment, a partner's keyboard, or a baby's hyper-sensitivity to small clicks and creaks.
White noise has equal energy at every frequency, which makes it bright and slightly hissy. That brightness is its strength: it masks high-pitched and sudden sounds more effectively than warmer colored noises. If your problem is conversations, electronics, or a noisy hallway, white noise is usually the best place to start.
Pink noise pulls some energy out of the high end, so it sounds gentler than white noise while still covering a wide range of sound. If pure white noise feels too sharp after a few minutes, pink noise is often the next thing to try. It is also commonly used in deep-sleep research because it pairs well with slow-wave brain activity.
Brown noise pushes even more energy toward the low end, producing a deep, room-filling rumble. It is often the best fit for masking traffic, HVAC hum, or low rolling sounds. If white noise feels too bright at night but you still want the masking benefit, brown noise is worth a try.
White noise is a good first choice for falling asleep in a shared home, blocking office chatter while you work, calming a fussy infant who startles at small sounds, and reducing the perceived intensity of tinnitus. Start the player above, set the volume just high enough to soften the room, and use the built-in timer if you only need help falling asleep. If white noise feels harsh after a while, switch pills and compare pink or brown — the best sound is the one you stop noticing first.
For most people, yes. A steady sound floor reduces the contrast between silence and sudden noises, which is what wakes you up at night. Several small studies have shown faster sleep onset and fewer awakenings in noisy environments.
At moderate volumes, yes. The American Academy of Pediatrics recommends keeping sound machines below 50 dB and placed at least seven feet from a crib. See our baby sleep guide for a fuller setup checklist.
Yes. Echo Sleep's web player runs as long as the browser tab is open. For phones and tablets, the mobile app keeps playing in the background and includes a sleep timer if you prefer to stop the sound after you fall asleep.
